In the emperor penguin courtship call, male vocalizations are composed of long, slow bursts with lower frequency tones than the female version. But calls of SeaWorld San Diego male penguin E-79 defied this binary. Also unusual was this penguin’s male companion, E-81. The pair “kept company” and sometimes exhibited ritual courtship displays.
Researchers have significantly improved the accuracy of global geodetic parameters by employing Satellite Laser Ranging (SLR) to a wider array of Global Navigation Satellite System (GNSS), satellites, according to a recent study. This advancement aids crucial applications in geosciences and satellite navigation.
New study reveals that solid-state reaction process would occur among multiphase multicomponent ceramic during ablation, thereby, resulting in their composition evolution. This composition evolution led to the improvement of thermodynamic stability of multiphase multicomponent ceramic and enhanced its ablation performance.
Using a comprehensive global dataset including 27,297 measurements of wood density from 2,621 tree species worldwide, we test the hypothesis that the legacy of evolutionary history plays an important role in driving the variation of wood density among tree species.
New research led by Children’s Hospital Los Angeles has found that racial and socioeconomic disparities contribute to delayed care for craniosynostosis—a rare birth defect that occurs when a baby’s skull bones close too early.In the study, being Black/African American, having public insurance and living in an economically disadvantaged area were all risk factors for presenting for a first consultation at older ages.
Leptospirosis is an illness caused by a bacteria called leptospira that can be present in soil and stagnant water. Rodents and other wildlife carry the bacteria and spread it through their urine. Both humans and dogs can become sick with leptospirosis, while cats are considered disease-resistant. For both people and dogs, the result of infection can range from mild to deadly serious.
An interdisciplinary team of scientists from Jefferson Lab, Old Dominion University and the DOE’s Oak Ridge National Laboratory have developed a conceptual device for quantum computing that could rival – or even outperform – other systems being developed. The “core” of this computer would be based on a compact, spin-transparent storage ring, which can maintain the entangled states of ions as they travel along a figure-eight path.
